But let me add something... it's important to balance your squad with young and experienced players, young players improve way faster and in a couple training sessions you can raise his value and sell him for profit... Also, they take longer to get tired, so you can line them in a couple more matches than old players before rest them. You also need experienced players to use as captain and to balance team maturity!
